E. H. PARETS AGENT United States Patent 3,198,445 YARN WINDING APPARATUS William T. Hull, 3n, Rock Hill, S.C., and Eugene H. Parets, Decatur, Ala, assignors to Monsanto Company, a corporation of Delaware Fiied Oct. 25, 1963, Ser. No. 318,939 6 (Ilaims. (Cl. 242-18) This invention relates to yarn winding apparatus, and more particularly relates to such apparatus adapted to wind yarn packages having readily accessible transfer ends or tails as commonly referred to in textile usage.

In textile applications as war-ping, reeling and fabric weaving, it is necessary to provide a continuous uninterrupted flow of yarn traveling to processing machines. Creels are filled with packaged bobbins and a train of yarn is formed by tying or bonding the outer end of each yarn package to the inner end of each preceding package to be processed. The outer end on a package of yarn wound on a bobbin is easily accessible; however, the inner end is difiicult to reach unless the first length of yarn delivered to the bobbin when it is packaged is not hidden within the convolutions of the yarn. The term transfer tail is used herein to refer to the inner end or that portion of yarn which is first applied to a bobbin or holder. Transfer tails are formed on drawtwisted tape yarn packages by conventional drawtwist machinery. However, ordinary winding and drawwinding apparatus is not adapted to provide transfer tails on yarn packages since the end use of such yarn packages did not require transfer tails. Recently, however, there has been a demand for yarn packages with transfer tails other than drawtwisted yarn packages.

It is an object of this invention to provide yarn winding apparatus adapted to form yarn packages with transfer tails.

Another object is to provide yarn drawwinding apparatus adapted for forming transfer tails on yarn packaged on bobbins.

A further object is to provide yarn winding apparatus having a plurality of string-up Winding positions and adapted to form transfer tails simultaneously on each yarn package formed at each string-up position.

Other objects of the invention will in part be obvious and will in part appear hereinafter.

The novel winding apparatus according to one construction of .the invention comprises a plurality of downwinding positions each provided with a source of yarn and a feed-draw roll assembly for drawing the yarn. At each position a driven traverse device having peripheral groove means acts to displace the yarn back and forth across the face of a take-up bobbin on which the yarn is collected. A yarn transfer tail on the take-up bobbin is formed immediately before packaging the yarn on the bobbin by directing the yarn from the feed-draw roll assembly into engagement with a latch means positionable to a release position by control means. The yarn travels from the latch means to a threading roll provided with a threading rib adjacently located to and driven with the traverse device and moves therefrom .to a driven waste spool positioned next to the take-up bobbin and driven therewith. After taking up a sufiicient amount of substandard waste yarn on the waste spool the control means is operated to simultaneously release the latch means for disengaging the yarn therefrom. The yarn upon disengagement from the latch means assumes an angular path of travel to the threading roll, contacts the threading rib of the threading roll and is threaded into the traverse means while simultaneously being transferred from the waste spool to the take-up bobbin. Before the yarn is packaged on the take-up bobbin several convolutions or 3,198,445 Patented Aug. 3, 1965 Ice Wraps of yarn are taken up on the bobbin and these wraps after the bobbin is packaged furnish the transfer tail.

A more detailed and thorough understanding of the invention will be gained by referring to the following description and the accompanying drawing:

In the drawing:

FIGURE 2 is a side elevation view partly in section showing a preferred type of latch device;

FIGURE 3 is a cross-section taken through 3-3 of FIGURE 1 on an enlarged scale showing the structure of the threading roll; and

FIGURE 4 is a cross-section taken through 44 of FIGURE 1 on an enlarged scale showing theconstruction of the yarn waste spool. t

Like reference numerals are used to refer to similar components in the various figures in the drawing.

Referring to the drawing, a preferred embodiment of the invention is shown comprising a multiple position drawwinding apparatus for forming yarn packages provided with transfer tails. Two positions are illustrated; however, it will be understood that in practice a yarn drawwinder has many more positions mounted on a framework with one line of positions on one side and another line on the opposite side thereof in back-to-back relationship. Since each position is similar, the description as much as possible will be confined to a single yarn drawwinding position. A yarn source, such as a cake of nylon yarn l, is provided near a pair of engaging feed rolls 2 and 3, an idler roll and a driven roll, respectively. The yarn is extended from cake 1 through a pigtail guide 4 and travels between rolls 2 and 3 for delivering the yarn to a draw roll 5 at a preselected rate of speed. The yarn is laced in several common wraps around the draw roll 5 and a separator roll or guide 6 positioned near the draw roll 5. The draw roll 5 is driven at a faster rate of speed than is feed roll 3causing the yarn to be stretched therebetween, and a draw pin 7 is located between the driven rolls to localize stretching of the yarn.

A traverse drum 8 is located below the separator roll 6 and is mounted on a shaft 9 driven by a motor 10. The drum 3 is located, preferably, so that the yarn when extending vertically downwardly from the separator roll 6 travels on a course perpendicular to the axis of shaft 9 and cent-rally to the face of drum 8. A continuous sinuous or winding traverse groove 11 such as a single or double cycle groove for effecting a single or double traverse of the yarn for each revolution of the drum is formed about the peripheral surface on the face of drum 8. The winding groove 11 is open to one side of drum 8 through a slot 12 formed in traverse drum 8. I

Adjacent the slotted side of traverse drum 8 there is a threading roll-13 coaxially arranged and, preferably, integrally formed with drum 8. The threading roll 13 has a flange 14 formed outwardly from the traverse drum 8 and has a circumferential discontinuous threading rib 15 formed about the periphery thereof. The threading rib 15 substantially surrounds the threading roll 13 and has one end curved toward the flange 14 and the opposite end curved toward the traverse drum 8 adjacent slot 12 so that a labyrinthian spiral path or surface is provided windr ing from the surface of the threading roll 13 adjacent flange 14 to the traverse groove 11 via slot 1-2.

Below the traverse drum 8, a bobbin 16 is rotatably mounted on a spindle 17 extending from a pivotal lever 18 and arranged parallel with shaft 9. The face of bobbin 16 is preferably wider than the face of traverse drum 8. A waste spool 19 is coaxially arranged on spindle 17 between lever 18 and bobbin 16 and is adapted to rotate with bobbin 16 on spindle 17. Waste spool 19 has a yarn collecting surface formed between a pair of spaced flanges and has a plurality of spaced pins 20 extending from the outer flange in the direction of bobbin 16 overhanging a portion of the surface between the flanges. A plurality of transverse grooves 20a are formed in the face of spool 19. A drive roll 21 driven at a variable rate of speed by a motor 22 through a shaft 23 normally contacts bobbin 16 and surfacely drives the latter as well as spool 19. Bobbin 16 is driven by drive roll 21 at a constant peripheral rate of speed.

Threading roll 13 and waste spool 19 are arranged on corresponding sides of traverse drum 8 and bobbin 16, respectively, and are aligned in the same substantially vertical plane.

' A latch device 24 is positioned between separator roll 6 and traverse drum 3 and is aligned in the same substantially vertical plane with threading roll 13. One type of latching device is shown in FIGURE 2. An elongated stem 25 is swingably mounted in a latch bracket 26 by a spring means 27 that biases the stem 25 away from bracket 26. A latch 28 having a handle end and a hooked end is pivotally mounted in the bracket 26 intermediate its end and is biased by a spring 29 so that the hooked end is biased into contact with a notch 30 formed in the latch bracket 26. As shown in FIGUR 1 latch device 24 is positionable to a locked position with the stem 25 being held within notch 36 by the hooked end of latch 28. By moving the handle end of latch 28 counterclockwise against the force of spring 29 (FIGURE 1) stem 25 is released so that it moves away from notch 30. Latch 23 can be moved manually or automatically as shown in FIGURE 1 'by means of a collar 31 having a bar 32 extending therefrom and mounted on a rod or shaft 33 which is shifted rightward and leftward by such as a pneumatic cylinder 34. Collar 31 is positioned on rod 33such that the handle end of latch 28 is always in engagement with the bar 32 of collar 31. A valve 35 having a handle 36 positionable to an on and off position controls the supply of air under pressure to the pneumatic cylinder.

In a .multiple position arrangement, rod 33 has a plurality of collars 31 and actuation of rod 33 controls the operation of a plurality of latches 28 simultaneously in the same manner as explained for a single position, shaft 9 drives a plurality of traverse drums 3 and threading rolls 13, and the drive roll shaft 23 drives a plurality of drive rolls 21 permitting gang operation. The valve 35 is shown in FIGURE 1 in the off position. When the handle is placed in the on position, .air under pressure is supplied to cylinder 34 from a suitable source thereof and rod 33 is shifted leftward as viewed in FIGURE 1.

In operation, valve 35 is initially placed in the on position as shown in FIGURE 1 so that rod 33 is then in its furthermost rightward position thereby positioning the latch devices 24 in a locked position. The stems 25 of each latch device 24 are then locked within re spective notches 30 by latches 28 at which time each stem 25 is located over the face of each threading roll 13.

The separator rolls 6 are located over the traverse drums 8iand, preferably, centrally of the face of the drums 8. Initially, the yarn from cake 1 is extended through the pigtail guide 4, between the feed rolls 2 and 3, around the draw pin and is laced in several common wraps around the draw roll 5 and separator roll 6.

At each position, the yarn from the separator roll 6 is laced so as to pass over stem 25 of latch device 24 and is then extended in a straight line path engagingly over the surface of threading roll 13 adjacent flange 14 and downwardly to waste spool 19, several wraps of the yarn being taken about spool 19. The draw winder is then operated to take up the first length of yarn on the waste spool 19. Generally, the first length of yarn is sub-standard in quality and for this reason is col- Cit lected on waste spool 19. The yarn while being taken up on the waste spool 19 at this time merely passes over the surface of the threading roll 13. After a sufficient amount of yarn is taken up on the waste spool 19, handle 36 of valve 35 is moved to the on position, as shown in FIGURE 1 with broken lines, for charging the pneumatic cylinder 34 withtair under pressure. Cylinder 34 then shifts rod 33 leftwardly (FIGURE 1) and thus rocks the latch 28 counterclockwise to a release position thereby releasing stem 25 from notch 30. At each position stem 25 swings away from engagement with the yarn and the yarn assumes an angular travelling course from separator roll 6 to spool 19 and moves into the rotating path of and into engagement with threading rib of threading roll 13. The curved surface of the threading rib 15 displaces the yarn'laterally into the labyrinthian or spiral path and as the threading roll 13 rotates the yarn is in constant engagement with the surface defining the spiral path and is moved laterally to the inner curved end of threading rib 15. The yarn engages the inner curved end of rib 1S and is threaded into the peripheral sinuous groove 11 of traverse drum 8 through slot 12.

While the yarn is slidingly displaced laterally by the spiral path on the threading roll 13 the yarn is also transferred from waste spool 19 to the bobbin 16 and begins to wrap around the end of the bobbin. The face of bobbin 16 is preferably wider than the face of drum 8 so that several convolutions of the yarn are taken up on the end of bobbin 16 before the yarn is laced within the winding groove 11 of traverse drum 8. Once the yarn is engaged within the groove 11 of drum 8 the yarn begins to be displaced reciprocally back and forth across the face of bobbin 16 and a yarn package is for-med thereon. After a package is formed, the operation of the .drawwinder is discontinued and each bob-bin is doifed or removed from its spindle 17. The inner end of the yarn on each package is connected to the yarn on the waste spool and must be severed therefrom. The yarn end attached to the bobbin is then affixed or secured to the bobbin with means such as a strip of tape. The first convolutions applied to each bobbin 16 before the yarn is reciprocally packagedon the face of bobbin 16 is separate from the package and provides a sufficient length of yarn for establishing a transfer tail. The draw wound packages formed now have accessible transfer tails and can be used in processes requiring the tying of yarn ends between bobbins.

The yarn gathered on the waste spool 19 moved therefrom by inserting a cutting tool, sors or the like, into the transverse slot a and cutting the yarn from the spool. If the yarn should break durmg operation at one of the positions, the yarn is readily relaced by hooking the yarn about one of the pins 20 provided on waste spool 19 with the employment of an :aspirator or sucker gun.

In order to wind a new package after a completed package has been doffed, stem is manually repositioned into the notch or bracket 26 and locked therein with latch member 23. If latch member 28 is positioned in its release position as shown in broken lines in FIG. 1, by placing handle 36 of valve in the off position rod 33 will be actuated rightward permitting latch member 28 to pivot clockwise and lock stem 25. If rod 33 is already in its furthest rightward position, latch member 28 can be manually pivoted away from the notch on bracket 26, stem 25 manually placed in the notch, and latch member then released to lock stem 25.

It will be understood that modifications and variations are contemplated within the spirit of the invention and the scope of the following claims, and that the invention is not intended to be limited by the construction of the preferred embodiment shown and described.
